The Acute Effect of Daily Caffeine Intake on Urination Parameters in Men With Lower Urinary Tract Symptoms

Listen to this summary

The authors aimed to investigate the acute effects of a single dose of caffeine on urinary flow parameters in men with lower urinary tract symptoms (LUTS). Their findings revealed that caffeine intake significantly increased maximum urinary flow rate and mean flow rate without affecting post-void residual volume, suggesting that short-term caffeine consumption does not negatively impact voiding dynamics in this population.
